.Sh DESCRIPTION
-The
-.Fn arc4random
-function uses the key stream generator employed by the
-arc4 cipher, which uses 8*8 8 bit S-Boxes.
-The S-Boxes
-can be in about
-.if t 2\u\s71700\s10\d
-.if n (2**1700)
-states.
-The
-.Fn arc4random
-function returns pseudo-random numbers in the range of 0 to
-.if t 2\u\s731\s10\d\(mi1,
-.if n (2**32)\(mi1,
-and therefore has twice the range of
-.Xr rand 3
+.Pp
+These functions use a cryptographic pseudo-random number generator to generate
+high quality random bytes very quickly. One data pool is used for all
+consumers in a process, so that consumption under program flow can act as
+additional stirring. The subsystem is re-seeded from the kernel random number
+subsystem on a regular basis, and also upon
+.Xr fork 2 .
+.Pp
+This family of functions provides higher quality random data than those
+described in
+.Xr rand 3 ,
+.Xr random 3 ,
and
-.Xr random 3 .
+.Xr rand48 3 .
+They can be called in almost environments, including
+.Xr chroot 2
+and their use is encouraged over all other standard library functions for
+random numbers.
+.Pp
+.Fn arc4random
+returns a single 32-bit value.
.Pp
.Fn arc4random_buf
-function fills the region
+fills the region
.Fa buf
of length
.Fa nbytes
-with ARC4-derived random data.
+with random data.
.Pp
.Fn arc4random_uniform
-will return a uniformly distributed random number less than
+will return a single 32-bit value, uniformly distributed but less than
.Fa upper_bound .
-.Fn arc4random_uniform
-is recommended over constructions like
+This is recommended over constructions like
.Dq Li arc4random() % upper_bound
as it avoids "modulo bias" when the upper bound is not a power of two.
-.Pp
-The
-.Fn arc4random_stir
-function reads data from
-.Pa /dev/urandom
-and uses it to permute the S-Boxes via
-.Fn arc4random_addrandom .
-.Pp
-There is no need to call
-.Fn arc4random_stir
-before using
-.Fn arc4random
-functions family, since
-they automatically initialize themselves.
-.Sh EXAMPLES
-The following produces a drop-in replacement for the traditional
-.Fn rand
-and
-.Fn random
-functions using
-.Fn arc4random :
-.Pp
-.Dl "#define foo4random() (arc4random() % ((unsigned)RAND_MAX + 1))"
+In the worst case, this function may require multiple iterations
+to ensure uniformity.
+.Sh RETURN VALUES
+These functions are always successful, and no return value is
+reserved to indicate an error.

.Sh HISTORY
-.Pa RC4
-has been designed by RSA Data Security, Inc.
-It was posted anonymously
-to the USENET and was confirmed to be equivalent by several sources who
-had access to the original cipher.
-Since
-.Pa RC4
-used to be a trade secret, the cipher is now referred to as
-.Pa ARC4 .
+The original version of this random number generator used the RC4 (also known
+as ARC4) algorithm. In OS X 10.12 it was replaced with the NIST-approved AES
+cipher, and it may be replaced again in the future as cryptographic techniques
+advance. A good mnemonic is
+.Dq A Replacement Call for Random .

+multiples of a gigabyte by specifying a number followed by ``G'' or
+``g''.
+Multiples must be integers.

.Sh DESCRIPTION
The
.Fn usleep
function suspends execution of the calling thread until either
-.Fa useconds
-microseconds have elapsed
-or a signal is delivered to the thread whose action
-is to invoke a signal-catching function
-or to terminate the thread or process.
-The actual time slept may be longer, due to system latencies
-and possible limitations in the timer resolution of the hardware.
+.Fa microseconds
+microseconds have elapsed or a signal is delivered to the thread and its
+action is to invoke a signal-catching function or to terminate the
+process.
+System activity or limitations may lengthen the sleep by an indeterminate amount.
.Pp
-This function is implemented, using

+This function is implemented using

by pausing for
-.Fa useconds

microseconds or until a signal occurs.
Consequently, in this implementation,
-sleeping has no effect on the state of process timers
+sleeping has no effect on the state of process timers,
and there is no special handling for SIGALRM.
+Also, this implementation does not put a limit on the value of

+The string is null terminated, and a pointer to the end of the string is
returned.
The maximum length of any encoding is four
-characters (not including the trailing
+bytes (not including the trailing
.Dv NUL ) ;
thus, when
encoding a set of characters into a buffer, the size of the buffer should
-be four times the number of characters encoded, plus one for the trailing
+be four times the number of bytes encoded, plus one for the trailing
.Dv NUL .
-The
-.Fa flag
-argument is used for altering the default range of
+The flag parameter is used for altering the default range of
characters considered for encoding and for altering the visual
representation.
The additional character,
encoding format (explained below).
.Pp
The
-.Fn strvis
+.Fn strvis ,
+.Fn strnvis ,
+.Fn strvisx ,
and
-.Fn strvisx
+.Fn strnvisx
functions copy into
.Fa dst
a visual representation of
.Fa src .
The
.Fn strvis
-function encodes characters from
+and
+.Fn strnvis
+functions encode characters from
.Fa src
up to the
first
.Dv NUL .
The
.Fn strvisx
-function encodes exactly
+and
+.Fn strnvisx
+functions encode exactly
.Fa len
characters from
.Fa src
The size of
.Fa dst
must be four times the number
-of characters encoded from
+of bytes encoded from
.Fa src
(plus one for the
.Dv NUL ) .
Both
-forms return the number of characters in dst (not including
-the trailing
+forms return the number of characters in
+.Fa dst
+(not including the trailing
.Dv NUL ) .
+The
+.Dq Nm n
+versions of the functions also take an additional argument
+.Fa dlen
+that indicates the length of the
+.Fa dst
+buffer.
+If
+.Fa dlen
+is not large enough to fit the converted string then the
+.Fn strnvis
+and
+.Fn strnvisx
+functions return \-1 and set
+.Va errno
+to
+.Dv ENOSPC .
+The
+.Fn strenvisx
+function takes an additional argument,
+.Fa cerr_ptr ,
+that is used to pass in and out a multibyte conversion error flag.
+This is useful when processing single characters at a time when
+it is possible that the locale may be set to something other
+than the locale of the characters in the input data.
+.Pp
+The functions
+.Fn svis ,
+.Fn snvis ,
+.Fn strsvis ,
+.Fn strsnvis ,
+.Fn strsvisx ,
+.Fn strsnvisx ,
+and
+.Fn strsenvisx
+correspond to
+.Fn vis ,
+.Fn nvis ,
+.Fn strvis ,
+.Fn strnvis ,
+.Fn strvisx ,
+.Fn strnvisx ,
+and
+.Fn strenvisx
+but have an additional argument
+.Fa extra ,
+pointing to a
+.Dv NUL
+terminated list of characters.
+These characters will be copied encoded or backslash-escaped into
+.Fa dst .
+These functions are useful e.g. to remove the special meaning
+of certain characters to shells.
.Pp
The encoding is a unique, invertible representation composed entirely of
graphic characters; it can be decoded back into the original form using
the
-.Xr unvis 3
-or
+.Xr unvis 3 ,
.Xr strunvis 3
+or
+.Xr strnunvis 3
functions.
.Pp
There are two parameters that can be controlled: the range of
-characters that are encoded, and the type
-of representation used.
-By default, all non-graphic characters
-except space, tab, and newline are encoded.
-(See
-.Xr isgraph 3 . )
+characters that are encoded (applies only to
+.Fn vis ,
+.Fn nvis ,
+.Fn strvis ,
+.Fn strnvis ,
+.Fn strvisx ,
+and
+.Fn strnvisx ) ,
+and the type of representation used.
+By default, all non-graphic characters,
+except space, tab, and newline are encoded (see

+Unsafe means control characters which may cause common terminals to perform
unexpected functions.
-Currently this form allows space,

.Pp
+(The above flags have no effect for
+.Fn svis ,
+.Fn snvis ,
+.Fn strsvis ,
+.Fn strsnvis ,
+.Fn strsvisx ,
+and
+.Fn strsnvisx .
+When using these functions, place all graphic characters to be
+encoded in an array pointed to by
+.Fa extra .
+In general, the backslash character should be included in this array, see the
+warning on the use of the
+.Dv VIS_NOSLASH
+flag below).
+.Pp
There are four forms of encoding.
-Most forms use the backslash character
+All forms use the backslash character
.Ql \e
to introduce a special
-sequence; two backslashes are used to represent a real backslash.
+sequence; two backslashes are used to represent a real backslash,
+except
+.Dv VIS_HTTPSTYLE
+that uses

+or
+.Dv VIS_MIMESTYLE
+that uses

These are the visual formats:
-.Bl -tag -width VIS_HTTPSTYLE
+.Bl -tag -width VIS_CSTYLE
.It (default)
Use an
.Ql M
to represent meta characters (characters with the 8th
bit set), and use caret
.Ql ^

-.Pf ( Xr iscntrl 3 ) .
+to represent control characters (see
+.Xr iscntrl 3 ) .
The following formats are used:
.Bl -tag -width xxxxx
.It Dv \e^C
Use C-style backslash sequences to represent standard non-printable
characters.
The following sequences are used to represent the indicated characters:

When using this format, the
.Fa nextc
-argument is looked at to determine

Use a three digit octal sequence.
The form is
.Ql \eddd
where

+.Em d
represents an octal digit.
+.It Dv VIS_HTTPSTYLE
+Use URI encoding as described in RFC 1738.

.El
.Pp
There is one additional flag,
.Ql M-C ) .
With this flag set, the encoding is
ambiguous and non-invertible.
+.Sh MULTIBYTE CHARACTER SUPPORT
+These functions support multibyte character input.
+The encoding conversion is influenced by the setting of the
+.Ev LC_CTYPE
+environment variable which defines the set of characters
+that can be copied without encoding.
+.Pp
+When 8-bit data is present in the input,
+.Ev LC_CTYPE
+must be set to the correct locale or to the C locale.
+If the locales of the data and the conversion are mismatched,
+multibyte character recognition may fail and encoding will be performed
+byte-by-byte instead.
+.Pp
+As noted above,
+.Fa dst
+must be four times the number of bytes processed from
+.Fa src .
+But note that each multibyte character can be up to
+.Dv MB_LEN_MAX
+bytes
+.\" (see
+.\" .Xr multibyte 3 )
+so in terms of multibyte characters,
+.Fa dst
+must be four times
+.Dv MB_LEN_MAX
+times the number of characters processed from
+.Fa src .
+.Sh ENVIRONMENT
+.Bl -tag -width ".Ev LC_CTYPE"
+.It Ev LC_CTYPE
+Specify the locale of the input data.
+Set to C if the input data locale is unknown.
+.El
+.Sh ERRORS
+The functions
+.Fn nvis
+and
+.Fn snvis
+will return
+.Dv NULL
+and the functions
+.Fn strnvis ,
+.Fn strnvisx ,
+.Fn strsnvis ,
+and
+.Fn strsnvisx ,
+will return \-1 when the
+.Fa dlen
+destination buffer size is not enough to perform the conversion while
+setting
+.Va errno
+to:
+.Bl -tag -width ".Bq Er ENOSPC"
+.It Bq Er ENOSPC
+The destination buffer size is not large enough to perform the conversion.

+.Sh NAME
+.Nm clock_gettime ,
+.Nm clock_settime ,
+.Nm clock_getres ,
+.Nm clock_gettime_nsec_np
+.Nd get/set date and time
+.Sh SYNOPSIS
+.Fd #include <time.h>
+.Ft int
+.Fn clock_gettime "clockid_t clock_id" "struct timespec *tp"
+.Ft int
+.Fn clock_settime "clockid_t clock_id" "const struct timespec *tp"
+.Ft int
+.Fn clock_getres "clockid_t clock_id" "struct timespec *tp"
+.Ft uint64_t
+.Fn clock_gettime_nsec_np "clockid_t clock_id"
+.Sh DESCRIPTION
+The
+.Fn clock_gettime
+and
+.Fn clock_settime
+functions
+allow the calling process to retrieve or set the value used by a clock
+which is specified by
+.Fa clock_id .
+.Pp
+.Fa clock_id
+can be a value from
+one of 5 predefined values:
+.Bl -tag -width Er
+.It Dv CLOCK_REALTIME
+the system's real time (i.e. wall time) clock, expressed as the amount of time
+since the Epoch.
+This is the same as the value returned by
+.Xr gettimeofday 2 .
+.It Dv CLOCK_MONOTONIC
+clock that increments monotonically, tracking the time since an arbitrary
+point, and will continue to increment while the system is asleep.
+.It Dv CLOCK_MONOTONIC_RAW
+clock that increments monotonically, tracking the time since an arbitrary point
+like CLOCK_MONOTONIC. However, this clock is unaffected by frequency or time
+adjustments. It should not be compared to other system time sources.
+.It Dv CLOCK_MONOTONIC_RAW_APPROX
+like CLOCK_MONOTONIC_RAW, but reads a value cached by the system at context
+switch. This can be read faster, but at a loss of accuracy as it may return
+values that are milliseconds old.
+.It Dv CLOCK_UPTIME_RAW
+clock that increments monotonically, in the same manner as
+.Dv CLOCK_MONOTONIC_RAW,
+but that does not increment while the system is asleep.
+The returned value is identical to the result of
+.Fn mach_absolute_time
+after the appropriate mach_timebase conversion is applied.
+.It Dv CLOCK_UPTIME_RAW_APPROX
+like CLOCK_UPTIME_RAW, but reads a value cached by the system at context
+switch. This can be read faster, but at a loss of accuracy as it may return
+values that are milliseconds old.
+.It Dv CLOCK_PROCESS_CPUTIME_ID
+clock that tracks the amount of CPU (in user- or kernel-mode) used by the
+calling process.
+.It Dv CLOCK_THREAD_CPUTIME_ID
+clock that tracks the amount of CPU (in user- or kernel-mode) used by the
+calling thread.
+.El
+.Pp
+The structure pointed to by
+.Fa tp
+is defined in
+.In sys/time.h
+as:
+.Bd -literal -offset indent
+struct timespec {
+ time_t tv_sec; /* seconds */
+ long tv_nsec; /* and nanoseconds */
+};
+.Ed
+.Pp
+Only the
+.Dv CLOCK_REALTIME
+clock can be set, and only the superuser may do so.
+.Pp
+The resolution of a clock is returned by the
+.Fn clock_getres
+call.
+This value is placed in a (non-null)
+.Fa *tp .
+This value may be smaller than the actual precision of the underlying clock,
+but represents a lower bound on the resolution.
+.Pp
+As a non-portable extension, the
+.Fn clock_gettime_nsec_np
+function will return the clock value in 64-bit nanoseconds.
+.Sh RETURN VALUES
+A 0 return value indicates that the call succeeded.
+A \-1 return value indicates an error occurred, and in this
+case an error code is stored into the global variable
+.Va errno .
+For
+.Fn clock_gettime_nsec_np
+a return value of non-0 indicates success. A 0 return value indicates an error
+occurred and an error code is stored in
+.Va errno .
+.Sh ERRORS
+.Fn clock_gettime ,
+.Fn clock_settime ,
+.Fn clock_getres ,
+and
+.Fn clock_gettime_nsec_np
+will fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+.Fa clock_id
+is not a valid value.
+.It Bq Er EFAULT
+The
+.Fa tp
+argument address referenced invalid memory.
+.El
+.Pp
+In addition,
+.Fn clock_settime
+may return the following errors:
+.Bl -tag -width Er
+.It Bq Er EPERM
+A user other than the superuser attempted to set the time.
+.It Bq Er EINVAL
+.Fa clock_id
+specifies a clock that isn't settable,
+.Fa tp
+specifies a nanosecond value less than zero or greater than 1000 million,
+or a value outside the range of the specified clock.
+.El
+.Sh SEE ALSO
+.Xr date 1 ,
+.Xr getitimer 2 ,
+.Xr gettimeofday 2 ,
+.Sh HISTORY
+These functions first appeared
+in
+Mac OSX 10.12
+.Sh STANDARDS
+The
+.Fn clock_gettime ,
+.Fn clock_settime ,
+and
+.Fn clock_getres
+system calls conform to
+.St -p1003.1b-93 .
+.Fn cleck_gettime_nsec_np
+is a non-portable Darwin extension.
+The clock IDs
+.Fa CLOCK_MONOTONIC_RAW
+and
+.Fa CLOCK_UPTIME_RAW
+are extensions to the POSIX interface.

+.Sh DESCRIPTION
+An array of strings called the
+.Ar environment
+is made available by
+.Xr execve 2
+when a process begins.
+By convention these strings have the form
+.Dq Ar name=value .
+The following names are used by various commands:
+.Bl -tag -width LC_MONETARY
+.It Ev BLOCKSIZE
+The size of the block units used by several commands, most notably
+.Xr df 1 ,
+.Xr du 1
+and
+.Xr ls 1 .
+This variable is processed by the
+.Xr getbsize 3
+function.
+.It Ev COLUMNS
+The user's preferred width in column positions for the terminal.
+Utilities such as
+.Xr ls 1
+and
+.Xr who 1
+use this to format output into columns.
+If unset or empty, utilities will use an
+.Xr ioctl 2
+call to ask the terminal driver for the width.
+.It Ev EDITOR
+Default editor name.
+.It Ev EXINIT
+A startup list of commands read by
+.Xr ex 1
+and
+.Xr vi 1 .
+.It Ev HOME
+A user's login directory, set by
+.Xr login 1
+from the password file
+.Xr passwd 5 .
+.It Ev LANG
+This variable configures all programs which use
+.Xr setlocale 3
+to use the specified locale unless the
+.Ev LC_*
+variables are set.
+.It Ev LC_ALL
+Overrides the values of
+.Ev LC_COLLATE ,
+.Ev LC_CTYPE ,
+.Ev LC_MESSAGES ,
+.Ev LC_MONETARY ,
+.Ev LC_NUMERIC ,
+.Ev LC_TIME
+and
+.Ev LANG .
+.It Ev LC_COLLATE
+Locale to be used for ordering of strings.
+.It Ev LC_CTYPE
+Locale to be used for character classification
+(letter, space, digit, etc.) and for interpreting byte sequences as
+multibyte characters.
+.It Ev LC_MESSAGES
+Locale to be used for diagnostic messages.
+.It Ev LC_MONETARY
+Locale to be used for interpreting monetary input
+and formatting output.
+.It Ev LC_NUMERIC
+Locale to be used for interpreting numeric input and
+formatting output.
+.It Ev LC_TIME
+Locale to be used for interpreting dates input and
+for formatting output.
+.It Ev MAIL
+The location of the user's
+mailbox instead of the default in /var/mail,
+used by
+.Xr mail 1 ,
+.Xr sh 1 ,
+and many other mail clients.
+.It Ev NLSPATH
+List of directories to be searched for the message catalog referred to by
+.Ev LC_MESSAGES .
+See
+.Xr catopen 3 .
+.It Ev PAGER
+Default paginator program.
+The program specified by this variable is used by
+.Xr mail 1 ,
+.Xr man 1 ,
+.Xr ftp 1 ,
+etc, to display information which is longer than the current display.
+.It Ev PATH
+The sequence of directories, separated by colons, searched by
+.Xr csh 1 ,
+.Xr sh 1 ,
+.Xr system 3 ,
+.Xr execvp 3 ,
+etc, when looking for an executable file.
+.Ev PATH
+is set to ``/usr/bin:/bin'' initially by
+.Xr login 1 .
+.It Ev PRINTER
+The name of the default printer to be used by
+.Xr lpr 1 ,
+.Xr lpq 1 ,
+and
+.Xr lprm 1 .
+.It Ev PWD
+The current directory pathname.
+.It Ev SHELL
+The full pathname of the user's login shell.
+.It Ev TERM
+The kind of terminal for which output is to be prepared.
+This information is used by commands, such as
+.Xr nroff 1
+or
+.Xr plot 1
+which may exploit special terminal capabilities.
+See
+.Pa /usr/share/misc/termcap
+.Pq Xr termcap 5
+for a list of terminal types.
+.It Ev TERMCAP
+The string describing the terminal in
+.Ev TERM ,
+or, if
+it begins with a '/', the name of the termcap file.
+See
+.Ev TERMPATH
+below, and
+.Xr termcap 5 .
+.It Ev TERMPATH
+A sequence of pathnames of termcap files, separated by colons or spaces,
+which are searched for terminal descriptions in the order listed.
+Having
+no
+.Ev TERMPATH
+is equivalent to a
+.Ev TERMPATH
+of
+.Dq Pa $HOME/.termcap:/etc/termcap .
+.Ev TERMPATH
+is ignored if
+.Ev TERMCAP
+contains a full pathname.
+.It Ev TMPDIR
+The directory in which to store temporary files.
+Most applications use either
+.Dq /tmp
+or
+.Dq /var/tmp .
+Setting this variable will make them use another directory.
+.It Ev TZ
+The timezone to use when displaying dates.
+The normal format is a pathname relative to
+.Dq Pa /usr/share/zoneinfo .
+For example, the command
+.Dq env TZ=America/Los_Angeles date
+displays the current time in California.
+See
+.Xr tzset 3
+for more information.
+.It Ev USER
+The login name of the user.
+.El
+.Pp
+Further names may be placed in the environment by the
+.Ic export
+command and
+.Ar name=value
+arguments in
+.Xr sh 1 ,
+or by the
+.Ic setenv
+command if you use
+.Xr csh 1 .
+It is unwise to change certain
+.Xr sh 1
+variables that are frequently exported by
+.Pa .profile
+files, such as
+.Ev MAIL ,
+.Ev PS1 ,
+.Ev PS2 ,
+and
+.Ev IFS ,
+unless you know what you are doing.
+.Pp
+The current environment variables can be printed with
+.Xr env 1 ,
+.Xr set 1
+or
+.Xr printenv 1
+in
+.Xr sh 1
+and
+.Xr env 1 ,
+.Xr printenv 1
+or the
+.Cm printenv
+built-in command in
+.Xr csh 1 .
+.Sh PROGRAMMING
+Programs can query and modify the environment, using the environment routines
+.Xr getenv 3 ,
+.Xr putenv 3 ,
+.Xr setenv 3
+and
+.Xr unsetenv 3 .
+Direct access can be made through the global variable
+.Va environ ,
+though it is recommended that changes to the enviroment still be made through
+the environment routines.
+.Pp
+Shared libraries and bundles don't have direct access to
+.Va environ ,
+which is only available to the loader
+.Xr ld 1
+when a complete program is being linked.
+The environment routines can still be used, but if direct access to
+.Va environ
+is needed, the
+.Fn _NSGetEnviron
+routine, defined in
+.In crt_externs.h ,
+can be used to retrieve the address of
+.Va environ
+at runtime.

-Programs can query and modify the environment, using the environment routines
-.Xr getenv 3 ,
-.Xr putenv 3 ,
-.Xr setenv 3
-and
-.Xr unsetenv 3 .
-Direct access can be made through the global variable
-.Va environ ,
-though it is recommended that changes to the enviroment still be made through
-the environment routines.
-.Pp
-Shared libraries and bundles don't have direct access to
-.Va environ ,
-which is only available to the loader
-.Xr ld 1
-when a complete program is being linked.
-The environment routines can still be used, but if direct access to
-.Va environ
-is needed, the
-.Fn _NSGetEnviron
-routine, defined in
-.In crt_externs.h ,
-can be used to retrieve the address of
-.Va environ
-at runtime.

-.Os
-.Sh NAME
-.Nm rcmdsh
-.Nd return a stream to a remote command without superuser
-.Sh SYNOPSIS
-.In unistd.h
-.Ft int
-.Fo rcmdsh
-.Fa "char **ahost"
-.Fa "int inport"
-.Fa "const char *locuser"
-.Fa "const char *remuser"
-.Fa "const char *cmd"
-.Fa "const char *rshprog"
-.Fc
-.Sh DESCRIPTION
-The
-.Fn rcmdsh
-function
-is used by normal users to execute a command on
-a remote machine using an authentication scheme based
-on reserved port numbers using
-.Xr rshd 8
-or the value of
-.Fa rshprog
-(if
-.No non- Ns Dv NULL ) .
-.Pp
-The
-.Fn rcmdsh
-function
-looks up the host
-.Fa *ahost
-using
-.Xr gethostbyname 3 ,
-returning \-1 if the host does not exist.
-Otherwise
-.Fa *ahost
-is set to the standard name of the host
-and a connection is established to a server
-residing at the well-known Internet port
-.Dq Li shell/tcp
-(or whatever port is used by
-.Fa rshprog ) .
-The parameter
-.Fa inport
-is ignored; it is only included to provide an interface similar to
-.Xr rcmd 3 .
-.Pp
-If the connection succeeds,
-a socket in the
-.Ux
-domain of type
-.Dv SOCK_STREAM
-is returned to the caller, and given to the remote
-command as stdin, stdout, and stderr.
-.Sh RETURN VALUES
-The
-.Fn rcmdsh
-function
-returns a valid socket descriptor on success.
-Otherwise, \-1 is returned
-and a diagnostic message is printed on the standard error.
-.Sh SEE ALSO
-.Xr rsh 1 ,
-.Xr socketpair 2 ,
-.Xr rcmd 3 ,
-.Xr rshd 8
-.Sh BUGS
-If
-.Xr rsh 1
-encounters an error, a file descriptor is still returned instead of \-1.
-.Sh HISTORY
-The
-.Fn rcmdsh
-function first appeared in
-.Ox 2.0 ,
-and made its way into
-.Fx 5.0 .

This is common with programs that were developed before
will result in a core dump due to
.Fn mkstemp
attempting to modify the string constant that was given.
-If the program in question makes heavy use of that type
-of function call, you do have the option of compiling the program
-so that it will store string constants in a writable segment of memory.

The
.Fn wprintf
family of functions produces output according to a
-.Fa format ,
+.Fa format
as described below.
The
.Fn wprintf
.Fn swprintf
and
.Fn vswprintf
-functions will fail if
+functions return the number of characters written (not including the terminating
+null wide character).
+These functions will fail (returning a negative value and setting
+.Va errno
+appropriately) if
.Fa n
-or more wide characters were requested to be written,
+or more wide characters were requested to be written.
+.Pp
+The other functions return the number of wide characters printed on success, or
+a negative value on faiure, setting
+.Va errno
+to indicate the error.
.Pp
The format string is composed of zero or more directives:
ordinary
.Vt double
argument is rounded and converted in the style
.Sm off
-.Oo \- Oc Ar d Li \&. Ar ddd Li e \\*[Pm] Ar dd
+.Oo \- Oc Ar d Li \&. Ar ddd Li e \(+- Ar dd
.Sm on
where there is one digit before the
decimal-point character
.Vt double
argument is converted to hexadecimal notation in the style
.Sm off
-.Oo \- Oc Li 0x Ar h Li \&. Ar hhhp Oo \\*[Pm] Oc Ar d ,
+.Oo \- Oc Li 0x Ar h Li \&. Ar hhhp Oo \(+- Oc Ar d ,
.Sm on
where the number of digits after the hexadecimal-point character
is equal to the precision specification.

.Sh DESCRIPTION
The
.Fn strptime
function parses the string in the buffer
-.Fa buf ,
+.Fa buf
according to the string pointed to by
.Fa format ,
and fills in the elements of the structure pointed to by
-.Fa tm .
+.Fa timeptr .
The resulting values will be relative to the local time zone.
Thus, it can be considered the reverse operation of
.Xr strftime 3 .
+The
+.Fn strptime_l
+function does the same as
+.Fn strptime ,
+but takes an explicit locale rather than using the current locale.
.Pp
The
.Fa format
are now interpreted as beginning at 1969 per POSIX requirements.
Years 69-00 are interpreted in the 20th century (1969-2000), years
01-68 in the 21st century (2001-2068).
+The
+.Fa \&%U
+and
+.Fa %W
+format specifiers accept any value within the range 00 to 53.
.Pp
If the
.Fa format
specify the resulting
.Vt struct tm ,
the unspecified members of
-.Va tm
+.Va timeptr
are left untouched.
For example, if
.Fa format
.Va tm_min
will be modified.
If time relative to today is desired, initialize the
-.Fa tm
+.Fa timeptr
structure with today's date before passing it to
.Fn strptime .
-.Pp
-While the
-.Fn strptime
-function uses the current locale, the
-.Fn strptime_l
-function may be passed a locale directly. See
-.Xr xlocale 3
-for more information.
.Sh RETURN VALUES
Upon successful completion,
.Fn strptime
It returns
.Dv NULL
if one of the conversions failed.
+.Fn strptime_l
+returns the same values as
+.Fn strptime .
.Sh LEGACY DESCRIPTION
In legacy mode, the
.Fa %Y
is taken as noon.
.Pp
The
-.Fa %U
-and
-.Fa %W
-format specifiers accept any value within the range 00 to 53
-without validating against other values supplied (like month
-or day of the year, for example).
-.Pp
-The
.Fa %Z
format specifier only accepts time zone abbreviations of the local time zone,
or the value "GMT".
